Raker and Beams

Stadium risers are used to support seating in stadiums, arenas, theaters and other types of grandstands. Typically, they are made as single, double or triple risers with heights cast to satisfy sight lines in the venue. Double risers are the most popular, but the type specified will depend on the layout and may be dictated by weights and crane access during construction.

Risers typically are 8 to 50 feet across and are cast in self-stressing forms made for each specific project. Up to three pieces are cast at once, depending on the lengths. The bottom and vertical sections of the riser are cast against the form and typically will remain as cast in the final construction.

The top (wearing surface) is typically troweled to the desired degree of smoothness or made slightly roughened to create a non slip surface.
